The gallbladder is a small organ under the liver that stores bile, a digestive fluid that helps break down fats in food. It releases bile into the small intestine when needed.
“Gallbladder” joins “gall,” an old word for bile, with “bladder,” meaning a sac or pouch. “Gall” comes from Old English “galla,” related to bitter fluids and sometimes bitterness in character.
